Market Making for Internship Interviews
Beginner-friendly market-making prep for quant internship interviews, including simple games, mental math, mocks, and a practical checklist.
Internship candidates learning market-making and trading-game basics.
Start with simple games
Internship candidates should first learn fair value, bid and ask, spread, inventory, and basic updates before trying complex related-market games.
Build mental math comfort
Market-making prompts often require quick percentages, averages, and expected values. Practice arithmetic inside quote drills, not only as isolated flashcards.
Concrete prep sequence
Do beginner quote drills, then one peer mock, then review every miss by category: fair value, spread, inventory, arithmetic, or communication.
Use a checklist
Before each quote, ask: what is fair value, how uncertain am I, what is my position, what size can I handle, and what new information would change this quote?
Common mistakes
Internship candidates often think they need obscure market knowledge. Most early prep should focus on clean reasoning and disciplined updates.
Practice the pattern
